IGNITEBFTORH Fon GAs-BURNERS.

To all whom 'it maypconcem: Be it known that we, J ULIUs F. RU'rz an JULIUS- K. LUETHE, both citizens of the United States, and residents of Milwaukee,

in the county of Milwaukeeand State of Wisconsin, post-oilice address 812 Brennan street, have invented certa-in new and useful Improvements in Igniter-Torches for Gas- Brners; and we do hereby declare that the fo lowing is a full, clear, and exact description thereof.

The primary object of our invention is to provide a snnple, economical `and effectiveigniter torch for gasburne-rs.\

Specificl objects are to provide a single torch abouit which a series of vvalve-controlled burners arev grouped within the Zone and upon'aplane common to individu/al jet flames that arr discharged. simultaneously from the torch; to provide aA torch head incased within an apertured bell, the apertures being alined with corresponding restricted gasoxygen inlthe air thereabout and thus re-, duce the efficiency of a centrally locatedl constant flame.

With; the above objects in View our invention consists in what is herein shown, described and claimed. f s

In the drawings Figure 1 represents a I plan view of a gas stove provided with a torch embodying the features of our invention; Fig. 2 an enlarged partially 'sectional elevation of the torch and its connection,

the torch being shown located within a stove which is indicated in dotted lines and having the bottom compartment `in full lines and in sections, there being a cross section of a portion of a burner located upon 'its proper plane relative to the igniter torch.

The section of the igniter torch being indicated by line 2 2 of Fig. 1. Frg. a, a detail Specification of Letters Patent. Application ilcd May 29,-1911.

trol and supplied with gas from a main pipe 3 in the ordinary manner. The branch pipe 4 having-.a valve is connected to the main pipe 3, said branch pipe being extended into.

the front wall and skeleton provided with aJ series of burners 2 under suitable valve-con the burner compartment, where it terminates V approximately at the center of the same and about which point theburners 2A are conveniently grouped. Coupled to the branchpipe 4 by an elbow .4 is a vertically disposed torch-head 5, which torch-head is providedwith a longitudinal channel 5 and terminates upon a plane slightly below the top grid.A The torch-head is also provided w1th a radially disposed gas-discharge aperture 6 for each burner, the apertures being disposed upoap-proximately the same horizontal plane as the burners whereby the latter are each within the zone of an individual y jet flame that is emitted from the gas-discharge apertures of said torch-head when Ia supply of gas is admitted thereto.-

The torch-head has 011e or more turesc below the gas discharge aperture 6, the leak apertures being staggereddn their horizontal plane relative to the plane f the kgas-discharge apertures whereby the latter are readily ignited, it being understood that gas from the leak-apertures is ignited. by a constant burning torch-nozzle 8, the mouth of which is in juxtaposition thereto but upon a. lower plane. l

The supply pf gas to the various torchf head apertures is ,regulated by a valve-plug 9 that is in threaded union with an opening which intersects the torch-head channel 5', the plug beingbelow the discharge and leak apertures' respectively and is adjusted to eii'ect the desired control of gas thereto. The torch-nozzle 8 is formed from a small tube or pipe that communicates with the mainsupply-pipe 3 and adjacent to its junction therewith, is equipped with a cut-oil" valve 8', which, under ordinary conditions,

leak aperis open, wherebygas is supplied in small Y quantities to the constant pilot flame. The end of the torch-nozzle is made fast to the torch-head by its engagement with an apertured clip 11 and should it be desiredto adjust the mouth of said nozzle relative to the leak apertures' said adjustment can be ef- .5 fected by springing the pipe 8'up or down so as to change the position of the mouth of the same relative to the leak-aperture and thereafter the said pipe is secured within the clip by a sfet-screwll that is in threaded lo engagement with the clip.

` The torch-head and pilot-light nozzle S are incased in a belld12, the top of which Ais secured to the upper end of said torchhead by a cap-screw 13 that is in threaded 15 engagement with the torch-head channel 5" whereby the same `is closed. The bell 12 is provided with a series of vent-holes 14, there being one for each gas-discharge aperture. These vent-holes are of considerably larger area than the discharge apertures and are in radial' alinement therewith whereby niames emitted from said apertures are di.

rected upon the various burners to cause ignit-ion of the latter when their valve-controlled gas pipes are opened. It is apparent from the foregoing description thatfin the operation of the torch the valve 8 .of the pilot-light is normally open, .J whereby a small dame is constantly maintained within the bell and, owing to its inclosed position, liability of the same to be f inadvertently blown out is practically eliminated. When it is desired to ignite one -or all of the burners grouped about the l torch the supply of gas thereto' is admitted by operating their individual cocks and thereafter the valve 4 which controls the gas-supply pipe 4 leading to the torch-head .1s opened. Gas will then pass out through 40 the discharge aperture 6 and also the leak aperture v`7, being slightly pocketed or conp inedwithin the top of the bell and simultaneously the torch nozzle 8 will y ignite this supply of confined gas, causing a slight y explosion which, in turn, will ignite the gas from the discharge apertures 6 and the ilame from each of said apertures `will be flashed .through the vent-holes of the bell and directed upon the various burnersv whereby they, in turn, will be ignited. 1t"

is apparentthat shoul only one of the burners be open to .th supply of gas no y .eect upon the remainin burners will be had. Attention is also cal ed to the fact that i .55 the airy for the supply of oxygen to the torch is drawn`in through the yspace between the mouth of the bell and the bottom 1, thel -intakeof air being thus upon' a considerably lower plane than the burners, thesupply of. sufficient oxygen for the torch'is in-y sured and furthermore the bottom of the bell being in juxtapositionto the bottom plate 1 said bell will eliectually shield the pilot-light from the disturbing influence of cross-currents of air. It will be observed that theI horizontally alined "vent-holes of the bell and dischargel apertures 6 are 'so arranged4 for-the purpose of discharging .the torch flame at the most convenient point for igniting the burner. We claim: 1. In agas stove provided with a group of burners; the combination of an igniter torch located approxima-tely centrally of the vgroup', the torch comprising a vertically dis- 75 posed headhaving` a. plurality ofrradially disposed apertures', each aperture being alined with a burner, a vertically disposed bell having aclosed top incasing the head, the bell being provided jvith radially dis- 8.0 posed vent holes, each being in register withv a head aperture, a pilot nozzle extending into the bell in' juxtaposition to the head apertures, and a gas supply means in communication with the head. i 2. An igniter torch comprising a vertically disposed head having a plurality of radially disposed apertures, a vertically disposedv closed bell'having a closed top `incasj ing the head, the bell being provided with a. series of radially disposed vent holes, each being in register'witha head aperture, a pilot nozzle extending into the bell in juxtaposition to the head apertures, and a gas upply means in communication with said ieac In a gas stove provided with a group of burners, the combination of an igniterl torch located approximately centrally of Athe group, comprising a valve-controlled gas- 100 supply pipe, a head in communication therewith'about which. the burners are grouped,

the head being providedl with an individual gas-discharge aperture lalined with each burner and leak apertures below the gas-discharge apertures, a vertically disposed'bell incasing the head provided with vent-holes each being in register with a gas-discharge aperture of the head, the mouth of the bell being vupon a lower planethan that of the 11o burners to form an air intake, means for securing the top of the bell to the head, means carried by the head for adjusting the flow of gas to its discharge apertures, and a pilotnozzle extending into the bell in juxta- ,11ur

position to the leak apertures of the headl `group, the torch comprising a vertically disposed head having a channel provided with gas discharge apertures adjacent to its upper end, each-aperture being alined with a burner, a vertically disposed bell fitted over the head provided with vent-holes in register with the head apertures, the mouth of the bell being upon a lower horizontal plane than that of the burners to form an airA intake shield whereby oxygen is supplied laov to the itorch and burner *flamesA from dierent stratas'of air, a, cap-screw 1n threaded-A l `the'gas-dischslgge apertures of said head.'

In testimony that 'We claim the foreoing we have hereunto set our hands at Mi Waukee in the county of Milwaukee and State of Wisconsin in the presencev of two Wtnesses. i
